ジャーナル フリーAn empirical relationship for the windage losses of a rotating inner cylinder in a concentric stationary outer cylinder was obtained as a function of the rotaing speed of the inner cylinder and the gap width between both cylinders, through analysis of theories by Taylor, Davey and Batchelor, and experiments by Wendt, Taylor and Donnelly. lnformation was also gained on the critical speed at which instability sets in, which depends on the gap width. The formula relating the friction factor f to rotating Reynolds number Red*, and to the ratio between gap width and radius d* can be applied to a range of Red* values from the critical value to about 200 times thereof and to a range of d* from 0 to 1, within an error of 30%.
Measurements of the windage loss of a Zippe-type gas centrifuge 34.9cm long with a radius of 5.20cm have been made for three mantle inner radii of 6.30, 7.04 and 8.20cm.
Experimental results plotted in f vs. Red* with d* as parameter agree well with the curves calculated by the present formula.抄録全体を表示PDF形式でダウンロード (608K) -

ジャーナル フリーBrief descripfion is given of the plan of construction of the proiected servicing home port for the nuclear ship. The location selected is the Port of Ominato in the northern part of Honshu and will be constructed in parallel with the building of Japan's first nuclear ship.
The port will support the operation of the nuclear ship with her shore servicing facilities, which will be prepared to refuel the marine reactor and treat radioactive wastes, as well as repair the reactor plant when necessary.
Among the major facilities to be constructed are a wharf crane, a service building for fuel handling and storing facilities, a waste freatment plant, a sub-staion and an office building.抄録全体を表示PDF形式でダウンロード (7381K) -
